Description

Technical Field

[0001] The invention belongs to the technical field of tooling, and in particular relates to a large-scale yarn winding forming machine. Background Art

[0002] At present, high-performance fiber materials have been widely used in many fields such as aviation, aerospace, national defense, automobiles and sports equipment. High-performance fiber tow boards are first constructed by winding flexible fiber materials into a hard rod-shaped structure, and then cut to obtain a plate structure of different thicknesses, showing excellent performance in ballistic impact, composite materials and other aspects. However, the formation of high-performance fiber tow boards is mostly carried out by manual winding, which has defects such as low winding efficiency, uneven winding density, difficulty in parallel winding of winding yarns, and unstable winding tightness. Based on this, it is necessary to develop a device to realize the automated production of tow board winding molding, improve efficiency, stabilize the quality of finished products, ensure uniform winding and consistent winding tension. For example, in the field of aerospace, the performance requirements of the board are extremely high, and the manual winding method is difficult to meet such high-precision and high-strength requirements. In automobile manufacturing, due to the large output, the low efficiency of manual winding will seriously affect the production progress. Therefore, it is imperative to realize automated production.

[0003] Patent publication number CN118289572A discloses a tow winding instrument, including a chassis; a first clamping mechanism, a second clamping mechanism; a winding mechanism, located on the axis of the line connecting the first clamping mechanism and the second clamping mechanism, and capable of reciprocating between the first clamping mechanism and the second clamping mechanism; a transmission mechanism, the winding mechanism is arranged on the transmission mechanism, and the transmission mechanism drives the winding mechanism to move; the winding mechanism includes a winding assembly, a rotating assembly and a motor I, and the winding assembly is arranged on the rotating assembly. The filament bundle rod can be prepared by the above-mentioned device. However, in the process of processing the filament bundle rod into a composite material board, it is still necessary to wind multiple filament bundle rods. For example, patent publication number CN117760266A discloses an ultra-light composite material board constructed by bionic tendon filament bundles, including n-level structure filament bundle rods, which are composed of several coaxially closely arranged n-1-level structure filament bundle rods fixed by yarn winding, wherein n≥3, and the primary structure filament bundle rod is composed of several fiber filaments fixed by yarn winding; the remaining space of the ultra-light composite material board is filled with resin. In practice, it is found that if the above-mentioned filament bundle winding instrument is used, many problems will occur when winding multiple filament bundle rods again. Due to the large volume and weight of the sample composed of multiple filament bundle rods, more than two workers are required to fix the two ends at the same time, and it is difficult to fix them with support, and the fixing strength of the clamp is required to be high; in addition, it is difficult for the clamp to tighten the sample, and radial bending of the filament bundle rod is prone to occur, and the winding tension is difficult to control. Summary of the invention

[0004] In view of the above technical problems, the present invention proposes a large-scale yarn winding forming machine. During the winding process, the wound yarn is subjected to the tensioning effect of a tension regulator and is detected in real time by a tension meter. The machine's pre-set rotation speed, spacing, and the impregnation of the wound yarn with resin in the gluing device avoid the instability of manual winding tension, the difficulty in controlling the steering angle, and the falling off after winding forming, thereby ensuring the strength of the filament plate and improving the winding efficiency.

[0039] Example 1

[0040] A large-scale yarn winding machine, such as Figure 1-7 As shown, the machine box includes a chassis 2, which is a shell or bracket in a rectangular, square or other shape, and is placed vertically on the ground to fix various components and protect some of them.

[0041] The first clamping mechanism 4 is fixed to the upper end of the chassis 2 and is used to clamp one end of the sample; the second clamping mechanism 5 is provided on the chassis 2 away from the first clamping mechanism 4 and close to the lower end and is used to clamp the other end of the sample. The first clamping mechanism 4 and the second clamping mechanism 5 are located on the same vertical line, and can ensure that the sample is vertical in the longitudinal direction when the sample is clamped. In addition, the second clamping mechanism 5 is fixed or relatively movable relative to the first clamping mechanism 4; for example, the second clamping mechanism 5 can be directly fixed to a certain position of the chassis 2. During the winding process, the distance between the first clamping mechanism 4 and the second clamping mechanism 5 cannot be adjusted, and only samples of corresponding lengths are wound.

[0042] The winding mechanism 6 is located on the axis of the line connecting the first clamping mechanism 4 and the second clamping mechanism 5, and can reciprocate between the first clamping mechanism 4 and the second clamping mechanism 5 to wind the yarn onto the sample.

[0043] The transmission mechanism 3 and the winding mechanism 6 are arranged on the transmission mechanism 3, and the transmission mechanism 3 is located on the inner side of the winding mechanism 6. The transmission mechanism 3 drives the winding mechanism 6 to move; the transmission mechanism 3 can be implemented by structures such as ball screws, slider guides, gear guides, and crawler chains.

[0044] The winding mechanism 6 comprises a winding assembly 61, a rotating assembly 62 and a motor I 63, wherein the winding assembly 61 is arranged on the rotating assembly 62; Figure 2 As shown, when the winding operation is performed, the sample passes through the rotating assembly 62, and the motor I 63 drives the rotating assembly 62 to rotate along the circumference of the sample, so that the winding assembly 61 winds the sample from top to bottom.

[0045] When the large-scale yarn winding machine is in use, the second clamping mechanism 5 and the winding mechanism 6 are moved to the bottom of the chassis 2. When holding the sample, a section of the sample is first fixed on the first clamping mechanism 4. The sample moves vertically downward under the action of gravity. The winding mechanism 6 moves up to allow the sample to pass through the rotating component 62, and then the other end is fixed through the second clamping mechanism 5. At this time, the sample is in a straight state and will not bend during the winding process. The yarn is set on the winding component 61 on the winding mechanism 6. In the initial state, the winding mechanism 6 is located at one end close to the first clamping mechanism 4. Driven by the transmission mechanism 3, the winding mechanism 6 gradually moves toward one end of the second clamping mechanism 5. At the same time, the motor I 63 drives the rotating component 62 to rotate along the circumference of the sample, so that the winding component 61 winds the sample.

[0046] Example 2

[0047] A large-scale yarn winding machine, such as Figure 1-7 As shown, it includes a chassis 2, which is arranged vertically on the ground; a first clamping mechanism 4, located at the upper end of the chassis 2, for clamping one end of the sample; a second clamping mechanism 5, arranged on one side of the lower end of the chassis 2 and away from the first clamping mechanism 4, for clamping the other end of the sample; a winding mechanism 6, located on the axis of the line connecting the first clamping mechanism 4 and the second clamping mechanism 5, and capable of reciprocating between the first clamping mechanism 4 and the second clamping mechanism 5; a transmission mechanism 3, the winding mechanism 6 is arranged on the transmission mechanism 3, and the transmission mechanism 3 drives the winding mechanism 6 to move; the winding mechanism 6 includes a winding component 61, a rotating component 62 and a motor I 63, and the winding component 61 is arranged on the rotating component 62; when working, the sample passes through the rotating component 62, and the motor I 63 drives the rotating component 62 to rotate along the circumference of the sample, so that the winding component 61 winds the sample.

[0048] Specifically, Figure 3 As shown, the first clamping mechanism 4 and the second clamping mechanism 5 have the same structure, including a clamp block I 451 and a clamp block II 452, which are stacked vertically and arranged on a lower connecting seat 454 and an upper connecting seat 453 respectively. The lower connecting seat 454 and the upper connecting seat 453 are arranged crosswise, do not affect each other, and are finally fixed to a clamp base 456 through a clamp connector 455. The clamp block I 451 and the clamp block II 452 both include a fixed screw, and a chuck is provided at both ends of the fixed screw. The chuck is sleeved on the fixed screw and can move along the fixed screw to realize a clamping opening with adjustable size between the clamp block I 451 and the clamp block II 452. The supporting surface of the chuck is V-shaped, and there are four chucks on the clamp block I 451 and the clamp block II 452 to form a rectangular clamping opening. In other embodiments, it can also be arc-shaped, and the shape of the chuck is determined according to the shape of the end of the sample.

[0049] In addition, the first clamping mechanism 4 and the second clamping mechanism 5 can also be used in conjunction with a fixed square box. By adjusting the distance between the clamping block I 451 and the clamping block II 452, a replaceable fixed square box of different sizes can be provided between the two. When the clamping block I 451 and the clamping block II 452 cannot achieve a good clamping and fixing effect on the sample, the fixed square box can be clamped between the two, and then the two ends of the sample are respectively placed in the fixed square boxes of the first clamping mechanism 4 and the second clamping mechanism 5, so that the sample can achieve a good clamping and fixing effect.

The linear module connector 35 is fixed on the linear module 31, and a ball screw is used between the two. The built-in guide rail 32 is a slide bar, which is located on both sides of the built-in guide rail 32 and inserted in the linear module connector 35 to play a directional role. Driven by the motor II 36, the linear module connector 35 moves along the built-in guide rail 32. In other embodiments, the linear module connector 35 and the linear module 31 can also be matched with a linear slide rail structure.

[0052] Specifically, a sample composed of multiple filament rods is clamped at both ends by the first clamping mechanism 4 and the second clamping mechanism 5, and is located on the same parallel line with the external guide rail 33 and the clamp moving guide rail 34. A winding mechanism 6 for winding the filament rod is provided on the chassis 2, and a locking assembly 51 for locking or unlocking the clamp on the external guide rail 33 and the clamp moving guide rail 34 is provided under the second clamping mechanism 5. The winding mechanism 6 is driven by the linear module 31 to wind the filament rod at a uniform speed along the axial direction of the filament rod. Sufficient space is left between the two external guide rails 33 and the clamp moving guide rail 34 for the circumferential rotation of the winding assembly 61, and the winding assembly 61 rotates around the axis of the filament rod.

[0053] The external guide rail 33 and the fixture moving guide rail 34 are respectively two parallel sliding rods and gear rods, the length direction of the sliding rod and the gear rod is parallel to the sample, and the first clamping mechanism 4 and the second clamping mechanism 5 are located between the two sliding rods and the gear rod.

[0054] Specifically, Figure 5 As shown, the locking assembly 51 includes a locking bolt 511 installed on the external guide rail 33, and the locking bolt 511 can be rotated to make it abut against the external guide rail 33 to fix the second clamping mechanism 5; the locking assembly 51 also includes a gear cover 513 installed on the clamp moving guide rail 34, and a gear set is arranged inside the gear cover 513, and the gear set is meshed with the clamp moving guide rail 34; the gear cover 513 is coaxially connected with the moving rocker 512, the safety pin 514, and the clamp connector 515 through the transmission rod, and the second clamping mechanism 5 is located between the two clamp connectors 515. Counterclockwise rotation of the moving rocker 512 can drive the second clamping mechanism 5 to move vertically upward along the external guide rail 33 and the clamp moving guide rail 34 through the clamp connector 515, and clockwise rotation of the moving rocker 512 and release of the safety pin 514 can drive the second clamping mechanism 5 to move vertically downward along the external guide rail 33 and the clamp moving guide rail 34 through the clamp connector 515.
